STOPPERING BOTTLES.

SPEGIFICATION forming part of Letters Patent No. 514,1 78, dated August 6,1895.

Application filed March 18, 1895. Serial No. 542,252. (No model.)

T0 all whom it may concern:

Be it known that I,WILLIAM JOSEPH KELLY, a subject of the Queen of Great Britain and Ireland, and a resident of 42 Stanley Street, Cheetham, Manchester, county of Lancaster, England,haveinventedcertainImprovements in Stopperihg Bottles, of which the following is a specification.

This invention relates to bottles and flasks provided with a removable back-pressure valve and seat capable of insertion into a bottle-neck after filling the said bottle, and also capable of being removed without breaking or injuring the bottle or any part of the device.

' The object of the said invention is to make such stoppers more durable and satisfactory, and the said invention consists in the con struction and combination of parts hereinafter set f0rth and claimed.

In the accompanying drawings, Figure 1 represents a vertical central section of a bottleneck and the upper part of a bottle provided with one form ot valve and valve-seat adapted to such use. Figs. 2, 3, 4:, and 5 represent similar views of other forms of the same, Fig. 2 omitt ing the bottle below the neck. Fig. 5 represents avertical sectional view of a bottleneck provided with a protecting cap or cover for the valve secured to the valve-seat, this being the preferred form of my invention, and Figs. 6, 6 7, and 7 represent detail views of modified forms of the valve and its seat.

In all of the said figures a designates the neck of the bottle or flask, b the valve having a stem b, and c a supportingring of rubber or other elastic material, which in Figs. 1, 2, and 3 constitutes also the valve-seat.

In Fig. 1 the periphery of the valve proper is provided with radially-extending guidestuds b which, by coming in contact with the inner face of the neck of the bottle, compel the said valve to rise and desceud vertically without tiltiug. A cross-bar b on the lower end of the valve-stem comes in contact with Y the under side of the valve-seat c, which is in 2'the said seat is much longer and thinner, retaining the annular form, but supporting the valve on an inwardly-extending annular bottom-fiange c having a central opening c instead of supporting iton the top of the said ring or annular seat, as in Fig. 1.

Fig. 3 is in all respects like Fig. 1, except that the annular seat c is provided with an external bead c surrounding its middle part and integral therewith, and fitting into a similarly-shaped recess formed by an outward bulge a of the bottle-neck.

-In Fig. 4 the neck is provided with this recess, which is made broader and more shallow, but the rubber ring c is made small enough to tit-therein with about one-half of the ring extending into a corresponding recess of an inelastic valve-seat e, which supports the said valve. At e, above and below the said ring, the said seat is of approximately the interior diameter of the bottle-neck. The ring c serves merely as a means of support and .removable attachment.

In Fig. 5 the rubber ring c is substantially that shown in Fig. 1, except that it has a convex exterior which fits into ashallow concavity provided for it in the inner face of the bottle-neck. In this instance the seat e is thinner than in Fig.4 and provided at the top with an outwardly-extending annular flange c which rests on the top of the said rubber ring, the body of the said seat fitting within the latter. In Fig. 5 this flange c is omitted, and the upper end of the said seat e,.extending above-the said ring, is externally screw threaded to engage similar threads on the inner face of the lower end of. a cap-shaped stop-frame d, which is screwed down against the said ring and has a central opening d" for the outward passage of the liquid. This frame prevents the valve from being dislodged if the cross-piece b should be detached or should fail to answer its purpose. Some times, as in Figs. 7 and 7 I use two of these crosspieces b, instead of one, with each valve- 5 provide its lower end with a nut to prevent detachment. The valve-seat c in this case has only its upper part made of rubber, the lower ICO part 0 being of inelastic material and providd with openings g for the passage of the liquid through its sides.

The operation of the valve while the bottle or flask is in use is substantially as in devices of the same general character already used and known. The same is true of its insertion and removal.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

A flat disk valve b provided with a stem b and cross-piece b in combination with a tubular valve seat e having its upper end screwthreaded, a stop-cap d which is screw-threaded 15 to turn on the said upper end, and a rubber ring c surrounding the said seat to hold it in the neck of a bottle the upper end of the said valve seat being extended above the said ring, substantially as set f0rth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM JOSEPH KELLY.
